If your brew basket begins to overflow, turn off the brewer. Allow the water to drain and the brew basket to cool before handling it.
Check the drip-stop
Manual drip-stop brew baskets
Make sure the drip-stop lever is fully open during the brew cycle.
Automatic drip-stop brew baskets
Make sure the carafe is positioned correctly beneath the brew basket. The carafe must engage the drip-stop mechanism for coffee to flow into the carafe.
Check the coffee and filter
An overflow can also occur when water cannot pass through the coffee and filter quickly enough. Check the following:
- Use a medium-coarse coffee grind.
- Do not exceed the recommended amount of coffee for your brewer.
- Use only one paper filter.
- Do not use a reusable mesh filter and a paper filter together.
- If using a reusable mesh filter, clean it thoroughly to remove coffee-oil buildup.
- Make sure coffee grounds have not spilled between the filter and brew basket.
Clean the brew basket
Remove and rinse the brew basket. Make sure its outlet and drip-stop mechanism are clean and free of coffee grounds or residue.

I have owned a KBT model for about a year. I love the machine, but even after following all of the guidance regarding grind size, water to coffee ratio, using Moccamaster filters, etc., I still struggle to brew a full 1.25 L carafe of coffee without the brew basket overflowing. Sometimes this can happen even making 1L of coffee. I am using a Capresso Infinity grinder and have it set to the courses settings and I am typically using coffee beans roasted within a week or two of brewing. Any ideas as to what would cause this to happen?
